INFO/WWW: Peptic ulcers may occure in the esophagus, the stomach, duodenum and Meckel`s diverticulum. Exacerbating factors are e.g. stress, smoking, alcohol, NSAID-steroids and Helicobacter pylori. The main dangers are gastrointestinal bleeding and perforation and erodation into other adjacent structures. Perforation may cause Pneumoperitoneum (air between e.g. the diaphram and liver or outside the bowel wall).
